BACKGROUND To measure the amounts of fluoride released from fluoride-containing materials, four glass ionomer cements (Fuji IX, Fuji VII, Fuji IX Extra and Fuji II LC), a compomer (Dyract Extra) and a giomer (Beautifil) were used in this study. METHODS Twenty cylindrical specimens were prepared from each material. The amount of released fluoride was(More)
The monoclonal antibody (mAb) Ki-67 is a marker for the growth fraction (GF) of tumor cells. The exact relationship between the Ki-67 labeling index (LI) and the conventional diagnostic criterion of the proliferative activity of brain tumors, the mitotic index (MI), is unknown except for some general references. On serial frozen sections Ki-67 LI and MI(More)
OBJECTIVES To compare curing performance of a second generation LED curing light with a high power tungsten quartz halogen (QTH). METHODS A hybrid composite resin (Filtek Z 250, 3M, USA) was used as test material and cured using a second generation LED light (Translux Power Blue™, Heraus Kulzer ,Germany) or a very high power QTH light unit (EMS,(More)
BACKGROUND As glass ionomers have the ability to reload fluoride from outside sources, the aim was to compare the recharge pattern of six glass ionomer cements after exposure to fluoride. MATERIALS AND METHODS Fuji VII, Fuji IX, Riva Pink, Riva Bleach, Ketac Fil and Fuji IX Extra were investigated. The fluoride-containing materials used were tooth paste(More)
BACKGROUND AND AIMS The aim of the present study was to compare the efficacy of quartz tungsten halogen (QTH) and light emitting diode (LED) curing lights on polymerization of resin composite. MATERIALS AND METHODS A hybrid resin composite was used to prepare samples which were cured using two QTH and ten LED light curing sources. Twelve groups, each(More)
